This image has a ghostly feel which compliments the subject, however technically, it looks like the photo may have been taken behind a glass partition.
I think I see reflections...was this taken through a window? A polorize filter can cut the reflections when taking pics through glass, but sometimes you still can't get rid of them all.
The piano is nice but the corner in the bottom left is distracting, as is the fact that the lantern tops have been cut off. Looks like it was taken through glass - is this an exhibit of some sort?
Taken through a glass window at a museum of some sort? Looks like reflections that are making your shot look ghostly. Perhaps a different angle would have led to less light reflecting?
